If it's to be a straight wiring deal, you might need cable drivers at the CPU end
N00B question: what's a cable driver?
How many PseudoSlots are already accessible on the SE/30 anyway? :?:
Consult gamba's SE/30 corner, or the Minitower SE/30 site. One or t'other of those pages has that info, I believe.
the Artmix Adapter's PAL / you shouldn't need it at all [for] SE/30 or IIsi cards
Well ... no. As the above two sites demonstrate. It's strictly for the IIci-PDS Daystar accelerators.
So are the PDS pass-through slots in series?
They're not physical slots, they're
pseudo-slot
addresses. And the cards themselves select their address (as I recall), not the Mac, nor any adapter. Most cards are hardwired to one address (or ID), some can be reset with jumpers. The
physical arrangement of cards matters not a whit, except insofar as which cards have a passthrough PDS, and physical space issues.
